Area of Science:

  • Urology
  • Endocrinology
  • Pathophysiology

Background:

  • Benign prostatic hypertrophy (BPH) is a common condition in aging men.
  • The exact mechanisms driving BPH development are not fully understood.
  • Hormonal influences are suspected to play a role in BPH pathogenesis.

Purpose of the Study:

  • To review the current understanding of BPH pathogenesis.
  • To evaluate the role of androgens and estrogens in BPH development.
  • To assess the efficacy of endocrine-targeted therapies for BPH.

Main Methods:

  • Literature review of studies on BPH pathogenesis and therapy.
  • Analysis of hormonal concentrations and enzyme activities in BPH.
  • Examination of treatment outcomes for androgen and estrogen deprivation therapies.

Main Results:

  • Elevated dihydrotestosterone and increased 5 alpha-reductase activity are linked to BPH.
  • Age-related changes in estrogen/testosterone ratios and estrogen receptors suggest hormonal involvement.
  • Therapies targeting androgen and estrogen withdrawal show symptomatic improvement in BPH patients.

Conclusions:

  • Dihydrotestosterone is a key factor in the pathogenesis of BPH.
  • Estrogen may also contribute to BPH development.
  • Endocrine-based therapies are effective for managing symptomatic BPH.
